. 5 Claims.

"I'his ihventidn relates to a dispensing 'or dis"- charge control device forcontain'ers.

such a's dental and talcum powder.

Anobject of'the invention is the provision of a device of the'indicated character which requires" agitation of a container contentsin order todis-' charge-a desired quantity therefrom.

A further object of the invention is the provision of a device of the indicated character which prevents the unintentional discharge of any of the contents of a container when the latter is disposed in a discharging position.

A further object of the invention is the provision of a simple and inexpensive device of the indicated character, and one which is of efiectual and substantial design.

With the foregoing, other objects of the invention will appear from the embodiment thereof, which by way of example is illustrated in the accompanying drawing, described in the following specification, and defined as to scope in the appended claims.

In the drawing:v

Fig. 1 is a perspective view of a container selected to illustrate the device of the present invention applied thereto.

Fig. 2 is a side view and part section of the con- 30 tainer disposed in a discharging position and 1llustrating the manner in which the device operates for the purpose of discharging some of the contents from the container.

Fig. 3 is a section taken approximately on the 5 line 3-3 of Fig. 2; and

Fig. 4 is a perspective View of the rotor which constitutes the agitating means of the device.

Referring now more particularly to the several views of the drawing, it will be apparent, that the 40 device of the present invention is shown in conjunction with a container consisting in the present instance of a body l and a cap H applied to the outlet end of said body l0. As shown, the cap ll conforms to and fits the outlet end of the body 10. In the present instance the cap consists of a wide portion l2 which merges into a relatively restricted portion [3. The wide portion l2 fits the outlet end of the body ID. The restricted portion i3 embodies substantially parallel side walls 14 and an arcuate wall I 5 between the walls 14 and joining the latter.

In accordance with the invention, the arcuate wall l5 of the cap II is provided with a series of discharge apertures or ducts or openings I6, and the same may be formed in any suitable manner 1937; Serial- No; 129,510 (01. 221-66) so as to impede the flow of the-material to bedischarged, and requires additional means which maybe manipulated to positively cause-the disa charge of the, desired quantityof the material from within the cap thru said apertures or ducts or'openings; To this end, the apertures etc. are outwardly restricted, and this is accomplished in thepresent instance by the material of the cap being directed inwardly as indicated at IT in Fig. 2.

In order to positively dispense or discharge a desired quantity of the contents of the container thru the restricted apertures etc., there is provided an agitating means in the form of a rotor l8. This rotor I8 is carried by the cap II. The rotor i8 includesan arbor I!) which is supported by the side Walls of the portion [2 of the cap I I. It is to be understood that the arc of the wall I5 is struck from the axis provided by the arbor iii. The rotor is constructed to provide radial members 20 on the armor l9, said members having flexible extremities 2! of rubber or any other suitable flexible material which are adapted to come in wiping contact with the arcuate wall l5 as indicated most clearly in Fig. 2. The extremities 2| serve for the purpose of positively causing the powder to be discharged from within the cap thru the ducts l6 when the container is disposed in an inverted or discharging position and while the rotor i 8 is being rotated. As stated, the ducts I6 are so formed as to impede the flow of material or powder and require the wiping action of the rotor IS in order to discharge the desired quantity of the material or powder. If desired, the rotor I8 may be provided with laterally extending wings 22 on the members 20 respectively. These wings 22 augment the action of the flexible extremities 2] in agitating the contents so as to obtain an easy flow thereof and to prevent clogging or compacting of the contents. In order to rotate the rotor IS, the arbor i9 is provided with a. knurled knob 23 which is exposed exteriorly of the cap II. By manipulating the knob 23 the rotor [8 may be readily rotated for the intended purposes.

The rotor l8 may be prevented from having axial movement by any suitable means such as the burrs 24 pinched from the material of the arbor l9.

The cap II is provided with shoulders 25 to accommodate a closure 26 which may be slid endwise into position to seal the ducts l6, said closure also having openings for slots to coincide with the ducts N5 of the cap II and which may be moved endwise and set so as to regulate,

rotor and disposed exteriorly of-the container to operate the rotor to cause said flexible portions to act on the contents of the container and thus discharge a desired quantity of the contents through said openings.

2. The combination with a container having an arcuate wall, said wall having a series of discharge openings, of a rotor within said container, said rotor having radial flexible wiping portions, and means connected with said rotor and disposed exteriorly of the container to operate the rotor to cause said flexible portions to act on the contents of the container and thus discharge a desired quantity of the contents through said openings.

3. The combination with a container having a series of discharge openings, of a rotor within said container, said rotor having radial members terminating in flexible agitating portions, and means connected with said rotor and disposed exteriorly of the container to operate the rotor to cause said flexible portions to act on the contents of the container and thus discharge a desired quantity of the contents through said openings.

4. In a device for dispensing granular material, a container for the material, said container having a multiplicity of outwardly restricted discharge ducts and means operable exteriorly of the container including an essentially flexible rotatable paddle-like member abutting against the inner parts of said ducts which acts on said material to positively eject desired quantities of the material from the container through said ducts.

5. In a device for dispensing powdered material, a container for the material, said container embodying an arcuate wall having a series of outwardly restricted discharge ducts, and a rotor supported by certain walls of the container to operate within the latter, said rotor having flexible wipers which move with respect to said arcuate wall and act on said material to dispense desired quantities of the material from the container through said ducts.
